readme: rewrite intro, add nav badges, reorder sections

- Plausible-style intro paragraph with inline "let us run it for you" link
- Replace plain text nav with for-the-badge styled buttons (website prominent, rest grey)
- Move "AI Spend Is a Blind Spot" before the three questions for stronger hook
- Rename "Why This Exists" to "What This Dashboard Answers"
